The design of an open-source carbonate reservoir model

This work presents a new open-source carbonate reservoir case study, the COSTA model, that uniquely considers significant uncertainties inherent to reservoirs, providing far more challenging and realistic benchmarking test for range of geo-energy applications. The field is large, with many wells large associated volumes. dataset embeds interacting geological petrophysical in an ensemble model concepts complexity levels varying production profiles. resulting number different models long run times creates demanding computational challenge than current models. takes inspiration from shelf-to-basin setting Upper Kharaib Member (Early Cretaceous), one most prolific aggradational parasequence formations sets world. based on 43 corresponding fully anonymised data northeastern part Rub Al Khali basin, sub-basin wider Arabian Basin. Our encapsulates large-scale heterogeneities found across profile, into single modelling simulation studies. result this research semi-synthetic but geologically suite capture wide geological, petrophysical, geomodelling can be history-matched against undisclosed, synthetic ‘truth case’. are made available as analyse several issues related testing numerical algorithms modelling, uncertainty quantification, simulation, history matching, optimization machine learning.
